Homological detection conjecture. If
Waldhausen's conjecture. There is a finite cover with .
Let be the fundamental group of a -manifold. A non-trivial element is a generalized torsion element if some non-empty finite product of conjugates of equals the…
Let be a compact -manifold with prime decomposition … where the prime factors are as in (1.1) and categories (i)–(iv): the are closed prime -manifolds with infinite…
Let be the fundamental group of a --manifold. A generalized torsion element is a non-trivial element whose non-empty finite product of conjugates is the identity, and is…
Planar boundary conjecture. Every visual boundary of is planar, and furthermore, is virtually the fundamental group of a compact 3-manifold.
Let be an admissible -manifold with first Betti number . Residual local indicability conjecture. The fundamental group is residually locally indicab…
Generalized-torsion conjecture. is bi-orderable if and only if has no generalized torsion element.
Mapping torus convergence-group conjecture. For any p-A-like element of , the mapping torus subgroup acts on as a convergence group.
Promotion of pseudo-fibering conjecture. There are three possibilities: is elementary; is a Fuchsian group; or is a closed hyperbolic -manifold group.
